The multifunctional novolac epoxy/Al 2 O 3 nanocomposites were fabricated by high-speed mechanical mixing of epoxy resin with varying concentration nano Al (0–5 wt%) particle size 13 nm for 30 min, followed curing triethylenetetramine (TETA) at 110°C 1 h and post-curing 80°C 5 h. nanocomposite samples characterized properties (viz., tensile strength, elongation-at-break, impact toughness, hardn...

Al(OH)3 nanoparticles were synthesized by a simple precipitation reaction. The effect of various amines like ethylene diamine, propylene diamine, triethylenetetramine and tetraethylenepentamine as precipitating agents on the morphology of Al(OH)3 nanostructures was investigated. The influence of Al(OH)3 nanoparticles on the flame retardancy of the poly vinyl alcohol (PVA) matrix was studied usi...

Breast cancer is characterized by overexpression of superoxide dismutase (SOD) and downregulation of catalase and more resistance to hydrogen peroxide (H2O2) than normal cells. Thus, relatively high H2O2 promotes breast cancer cell growth and proliferation. However, excessive intracellular H2O2 leads to death of breast cancer cells. In cancer cells, high level ascorbic acid (Asc) is able to be ...

Triethylenetetramine dihydrochloride (trien-2HCl; CAS No. 38260-01-04), a chelating agent used to treat Wilson's disease patients who are intolerant of the drug of choice, was tested for subchronic toxicity in B6C3F1 mice and F344 rats. Mice and rats received trien-2HCl in the drinking water at concentrations of 0, 120, 600, or 3000 ppm for up to 92 days. Twenty mice and 18 rats of each sex wer...
